There are several interpretations of the birth of the surname POSTON. Some say it comes from Old French word POSTERNE, from the time of the Norman invasion of England, which probably meant keeper of the back gate of a castle. Others say that the name POSSETORNE is in the DOOMSDAY BOOK that was ordered by William the Conqueror, at that time, so that people could be identified by surnames. There was a small tribe called POS and TON meant village or group, thus POSTON. There was a Lesser POSTON and is a Greator POSTON township of 640 acres called POSTON located near Ludlow, England. In 1251 POSTON and HOPTON are recorded in a dispute over common use of pasture recorded in a book, ANTIQUES of SHROPSHIRE, by EYTON.
